  • the present invention seeks to provide an improved inspection device.
  • an array of digital imaging devices arranged so that the field of view of each digital imaging device at least partially overlaps with the field of view of at least one other digital imaging device in order to facilitate the inspection of surfaces, spaces, animate and inanimate objects and public and private spaces.
  • the array is coupled to a processing system enabling the production of complete composite format images, such as landscape format images generated in real time or close to real time.
  • the output image and/or images may be automatically analysed.
  • automatic analysis can be performed by a computer system.
  • a composite image can be readily produced in real or quasi-real time as unlike providing a single mosaic image which is a seamless single image made up of a multiple of original images, a composite image comprises a single image made up of a plurality of original images wherein the seams between the images are discernable, so that the viewer can distinguish the original images.
  • Composite images are generated substantially without mathematic processing to merge image data.
  • Preferred arrays can be arranged to facilitate the inspection of surfaces, spaces, animate and inanimate objects and public and private spaces for security or safety purposes.
  • the analysed image or images may be processed prior to automatic analysis.
  • data output from said array is transmitted to a remote location.
  • the data may be transmitted via one or more of cable, fibre optics, infra-red, and/or radio frequency data.
  • the data to be transmitted is processed prior to transmission.

  • the portable device may be manoeuvred remotely by, for example, wireless control mechanisms.
  • Portable or fixed embodiments may be intended for the inspection of a vehicle, foreign object or material associated with a vehicle.
  • an array which is fixed removeably or otherwise in a pre-defined position.
  • surfaces or objects being inspected are moving, either before, after or during inspection. In most cases, surfaces or objects being inspected are moving past the array.
  • This type of embodiment is particularly used in, for example, the inspection of undersides of vehicles and surfaces or objects being produced in sheet form by batch or continuous process.
  • the vehicle may comprise a land vehicle, water craft or aircraft.
  • the inspection may be conducted while the subject is on land, underground, on water, underwater or in the air.
  • Preferred embodiments are also useful in the inspection of, for example, the exterior or interior of objects comprising pipes, chimneys, sewers, rooms, fluid tanks and/or other enclosed spaces.
  • the surface or object to be inspected may be a man made object or naturally occurring feature including waterway banks, land surfaces, water surfaces, roads, railways, runways, walls, ceilings and bankings.
  • comparison data are coupled to a memory or storage device so that comparison data can be stored and is available when the same object or surface is inspected again.
  • This comparison data may be, for example, a saved image or data from the first inspection.
  • comparison data on the subject can be retrieved from the store and processed to detect changes (if any).
  • comparison data comprises means for the recognition of individual vehicles
  • comparison data for vehicle recognition is based on a vehicle registration or other identification string or device.
  • Yet further prefaced embodiments are those in which image comparison information for an individual vehicle is stored in association with a vehicle identifier.
  • the data produced by said array is processed to form a three dimensional image.
  • data produced an array is processed to form an enhanced image.
  • An advantage of embodiments of the invention is that complete composite images (eg. landscape format) can be easily produced by combining the image data from two or more digital imaging devices in real time or close to real time. Such an image can then be displayed on a single display device.
  • complete composite images eg. landscape format
  • Another advantage of embodiments of the invention is that it enables automatic analysis of the image(s) by a computing system or other such devices.
  • a still further advantage of embodiments of the invention is that the digital format of the output data enables ready transmission over a range of potential mediums. Examples include transmission of the image data by cable, fibre optics, infrared, and/or radio frequency media.
  • the data produced by the arrays may be processed locally and/or remotely..
  • the digital imaging devices used in connection with embodiments of the present invention are readily available commercial items, and may be described as being an electronic imaging device in which the image data is captured in one of several digital formats which are compatible with the technical requirements to transmit the image data between computers through data networks.
  • a digital imaging device uses a detector which could be a charge coupled device (CCD) detector element to sense changes in light intensities and thereby configure the image.
  • CCD charge coupled device
  • the signals from the detector are processed into electronic data formats and structures which are compatible with the technical requirements to transmit the image data between computers through data networks such as the internet.
  • These devices can be placed in arrays of two or more, arranged so that the field of view of each digital imaging device at least particularly overlaps with the field of view of at least one other digital imaging device, so that the totality of the fields of view cover the whole of the scene to be monitored.
  • the arrays can be linear, as seen in Figure 1, in which the webcams 2 are linearly arranged on a base plate 6, so that each field of view 4 overlaps with at least one other field of view.
  • the digital imaging device 2 can be arranged along two axes, creating a two dimensional array, as seen in Figures 2 and 3, again with each field of view 4 overlapping with at least one other field of view.
  • Three dimensional arrays are also possible and may comprise a 2D array with one or more additional digital imaging devices 2 in a third axis, for example a pyramidal arrangement with a digital imaging device 2 at each node of the pyramid, as shown in Figures 3 and 5.
  • the digital imaging devices 2 may be individually enclosed for protection, or, substantially the whole array may be assembled inside a protective enclosure (not shown).
  • Preferred embodiments of the invention include the use of such an array to survey surfaces, spaces, animate and inanimate objects for security and/or safety reasons.
  • a particular embodiment of the invention is the use of such an array on a remotely controlled mobile device in order to inspect a surface, space, animate or inanimate object for the presence of foreign objects or materials.
